Paper Abstract
This study describes a color enhancement method that uses a color palette especially designed for protan and deutan
defects, commonly known as red-green color blindness. The proposed color reduction method is based on a simple color
mapping. Complicated computation and image processing are not required by using the proposed method, and the
method can replace protan and deutan confusion (p/d-confusion) colors with protan and deutan safe (p/d-safe) colors.
Color palettes for protan and deutan defects proposed by previous studies are composed of few p/d-safe colors. Thus, the
colors contained in these palettes are insufficient for replacing colors in photographs. Recently, Ito et al. proposed a p/dsafe
color palette composed of 20 particular colors. The author demonstrated that their p/d-safe color palette could be
applied to image color reduction in photographs as a means to replace p/d-confusion colors. This study describes the
results of the proposed color reduction in photographs that include typical p/d-confusion colors, which can be replaced.
After the reduction process is completed, color-defective observers can distinguish these confusion colors.
